crystal vs oscillator
I am researching a clock source to be used in a future project and I am little unsure about the difference between a crystal and an oscillator. We are gonna run a uController at 20mhz, and you can find that frequency in both types of clock sources. I see that some oscillators are called crystal oscillators. I understand the basic theory of how these work, but don't understand the differnces between the two. Can anyone help?
Also looking for help on how to make a PLL circuit for a pic micro that can use a PLL to clock up the speeds ...any help appreciated.
